Be Nice to Osiris (1 min)
(Hey, Osiris is back! Why don’t you talk to him and see how he is?)

-
Grow Onions (7 hrs)
(Osiris says he's been working at the lab on something very special for your preteen Sims. But before telling you what it is, he needs something from your Sims first. Onions! Grow some onions for one of Osiris's experiments.)

-
Be Nice to Osiris (1 min)
(Now that the onions are ready, give them to Osiris and ask him what he's working on.)-
Read the Big Book of Stuff (19+ hours)
(While browsing the internet on his ship, Osiris stumbled across a
number of ‘user reviews’ containing requests for preteen Sims to grow
up into teenagers! Wow, teenagers! Osiris says that he has started work
on a new device... and it’s nearly finished!
Osiris needs your help on the finishing touches. First, he needs your
Sim to read The Big Book of Stuff. There’s
a chapter in there on DNA.)

-
Watch a Movie Marathon (8+ hours)
(Great work! Don’t worry
about telling Osiris what you learned; he’s already harnessed the
information from your Sim telepathically! Okay... so while he continues
work on this device, why don’t you do some of your own research on
teenagers? Watch the American Pudding films. They’re about teenagers.)

-
Bake Chocolate
Pudding (2 hrs)
(That poor apple pie! Let’s make sure that there are no apple pies in
this house when your first teenager arrives. Let’s make sure there are
plenty
of other baked goods in the house. Say... chocolate puddings!) -
Talk to a Tree on a Housing Lot (5 hrs 30 mins)
(Hang on, who wrote these 'user reviews'? Who’s controlling the fate of
Sims? Uh-oh, one of your Sims is starting to question reality. Get one
of your Sims to talk to a tree in a housing lot. This might take a
while – your Sim suspects reality is an illusion and that they live
inside a simulation.
Note: To talk to a tree, bring a Sim to a housing lot and tap on one of
the trees located there.) -
Grow Potatoes (2 hrs)
(While your Sim was busy talking to the tree, Osiris was busy putting
the finishing touches on his new device. And guess what - it’s
complete! He’s going to install this device in all of your
Sims’ ovens. That way every single birthday cake will be able to grow a
preteen into a teen.
He just needs a small battery to power it. Did you know that potatoes
generate electricity?) -
Be Nice to Osiris (1 min)
(Okay, now that the potato battery is ready, Osiris should have
everything he needs to finish the device and upgrade your ovens. Be
nice to Osiris and give him the battery.)

-
Be Inconspicuous on a Park Bench (2 mins 42 secs, works at home)
(That’s it! Now you just need the instruction manual.
Unfortunately, he’s not going to give it to you here because he’s
afraid that someone... ‘out there’ might steal his technology. Wow,
this manual must contain some super secret information! Okay, let’s
organize a top secret meeting at the park. Go to the park bench and
wait for him there... and don’t forget to look inconspicuous!)

-
Bake a Birthday Cake (24 hrs)
(Finally! You’ve got the instruction manual!
Okay, Osiris has modified your ovens and now you’re ready to make a
birthday cake. The only thing you’re missing of course is the birthday
cake. Get cooking!)

You've
